SPECIFICATION forming part of 1 Letters Patent No. 731,667, dated June 23, 1903.- Application filed April 2, 1903. Serial No. 150,738. (No model.)

To all whom it may concerm.

Be it known that I, JOHN M. GoNRoY, a citizen of the United States, residing at Allegheny, in the county of Allegheny and'State of Pennsylvania, have invented or discovered certain new and useful Improvements in Machines for Ornamenting Glass, of which improvements the following is a specification, V

The invention described herein relates to certain improvements in machines for shaping r producing an ornamental effect in the edges of glass articles, such as mirrors, &c., and has for its object a construction and combination of mechanical devices whereby por-.

tions of the edges may be brokenaway in such manner as to produce an inclined scallop or indentationon the edge, a series of such scallops being produced bya regulated feed of the glass transversely of the line of the movement of the pin operatin g to produce the scallop.

The invention is hereinafter more fully def scribed and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan View of a form of apparatus embodying my improvement. Fig. 2 is a front elevation, and

Fig. 3 is a side elevation, of the same. Fig. 4L

isa sectional elevation. Figs. 5 and 6 are side and front elevations, respectively, of a modi fied form of the apparatus.

' In Letters Patent datedlVIarch 17,1902, No.

7 23,139,Ihave described and claimed a method" of ornamenting glass, which consists in strik-. ing the glass a series of sharp blows at points adjacent to its edge, the direction of impactbeing at an angle to the surface of the article,

and thereby breaking a piece of glass of such shape from the edge and opposite side of the article as to leave a scallop extending at an angle from the corner adjacent to which the blow was struck inward to a point some dis- In an application for Letters Patent, Serial No. 137,256, filed December 31, l 902,-I have described and claimed a mechanism whereby a series of scallops can be formed adjacent to each other,

such mechanism consisting, essentially, of a carrier having a series of two or more teeth so spaced on theface of the carrier as to, strike successively as regards time and at different points along the edge. In such a in a diagonal line across such face, so thatby one movement of the carrier one edge is shaped or operated on.

In the practice of the invention described herein I employ acarrier, which may be made in the form of a rotating drum or disk 1, as shown in Figs. 1 to 4, inclusive, or in the form of a reciprocating slide-head 1", as shown in Figs. 5 and On this carrier is secured a tooth 2, which in its movement will strike against a plate of glass supported by a tableor bearing portion 4. This table is shifted step by step to bring successive portions of the article into the plane of movement of the pin 2. When operating upon circular objects, the table 4 is carried by a shaft 6, driven through suitable interposed gearing 8 by the shaft 7. A ratchet-wheel 9 is secured on the shaft 7, and the pawl 10 is mounted on an arm 11, pivotally mounted 011 the shaft 7. The back-and-forth movement of the arm is effected through the link 12 by an eccentric-pin 13, carried by the shaft 14:, on which the drum or carrier 1 is mounted. By this'construction the table earryin g the article will be moved forward a predetermined distance on each revolution of the drum and pin, such distance being proportionately to the desired width of the scallop. In order to permit of varying the feed of the table, the pin 13 is adjustably mounted, as shown in Fig. 3. The articles are clamped on the table by a plate 15, loosely mounted on a screw 16, passing through the crossbar 17, secured to the frame of the machine. In order to insure that the axis of the plate 15 shall coincide with the axis of the table 4,'a disk 18 is loosely mounted on the hub of the clamping-plate 15 and is provided with a downwardly-projecting flange 19, which when the plate is screwed down passes inside of the rim 20 or the bed 21, supporting the table 4, as shown in Fig. 4:. 7

In the construction shown in Figs. 5 and G the carrier is formed by a reciprocating slide 1, mounted in suitable waysor guides 23. The slide or head is reciprocated by ICO means of a crank on the shaftl' i, onwhich is mounted a driving pulley or drum carrying the pin 13, which is adjustably mounted in said drum. A' link 12 connects the'pin with an arm 11,piv0tally mounted on a threaded shaft 27. On this arm is mounted a pawl 10, adapted to engage a ratchet-wheel 9, se-. cured to the threaded shaft. This shaft has engagement with the bed or table 4, which; is mounted in suitable guides 28. In order that the pin 2 may strike the edge of the article at the proper angle, the bed or table is; inclined, and the glass plate is secured thereto by any suitable means, such as a bent lever 29, pivoted to the table and adapted to have i one end forced down against the glass, clamping the same in position by a hand-screw 30, f passing through the opposite end of the lever and bearing against a suitable shoulder or abutment 31.

It will be understood by those skilled in the art that a reciprocating head may be em- 1 ployed to operate upon circular articles, and i vice versa a rotating head upon straight edges.

In operating the machine the feed movement is so adjusted that for each operative stroke of the carrier the bed or table carrying the glass is moved forward a distance equal to that of the desired spacing of the scallops.

I claim herein as my invention 1. In a machine for shaping the edges of glass articles, the combination of a movable carrier having a pin secured thereto, a table arranged to support the glass at an angle less than a right angle to the axis of the pin at the time of impact 011 the glass, and means for shifting the table step by step across the path of movement of the pin, substantially as set forth.

2. In a machine for shaping the edges of glass articles, the combination of a rotating carrier having a pin projecting radially therefrom, a table for supporting the glass, and means for shifting the table step by step across the path of movement .of the pin, substantially as set forth.

. In testimony whereof I have hereunto set my hand.

JOHN M. CONROY.
